Description: This fixes structuredClone() transfer-list validation for nested transfer conflicts. // This should fail, matching browser and other JavaScript runtime behavior. const t = new TransformStream(); structuredClone([t, t.readable],{ transfer: [t, t.readable] }); We already reject direct duplicate transfer entries, but validation could depend on transfer-list order when transferring a TransformStream together with one of its members. This could be handled in two ways: reject it when nested transferables create duplicates let serialization fail later with a lock error Nested transferables are currently expanded during validation, so this patch uses option 1. Option 2 would require broader changes to the current transfer design than this fix warrants.
